The $400m fight is less than a month away and McGregor has been doing whatever it takes to ensure he can pull off a massive upset against undefeated Mayweather inside the MGM Grand Arena - including sparring with former world champion Paulie Malignaggi.

The former fighter turned commentator revealed that McGregor certainly packs a punch.

He said: “Do you want to know if he hits hard? Yeah, I mean, he’s not a weak puncher. I’ll say that.

THE SPECIAL G-ONE

slap in the face

“People are dying for me to say, ‘Oh he hits hard!’ Oh, his big left hand.’ Listen, if Conor hits you, you’re going to feel it. He’s a grown man.

“I’d say he’s an above average puncher. If he lands a shot with 10 oz gloves, it will probably get your attention.

“Is it ‘Oh my God power’? No, ‘Oh my God power’ is very rare.

“More than anything he’s accurate and I think that’s what plays into the success he has with his punches. Nothing was like overwhelmingly powerful. I mean, he’s got power. He’s more accurate I’d say than anything.”
